MIDDIA High-Hardness Alumina Ceramic Plunger for Water Jet Loom (Item No. AC02)

Engineered specifically for high-speed water jet looms, textile machinery, and high-pressure fluid pumping, MIDDIA AC02 Alumina Ceramic Plungers deliver outstanding mechanical performance and extended operational lifespan. Crafted from high-purity Aluminum Oxide (Al2O3), this structural plunger component features exceptional hardness (Rockwell hardness HRA80-90, second only to diamond and boron carbide). Its wear resistance is far superior to standard stainless steel—outperforming high-chromium cast iron by 171.5 times and manganese steel by 266 times under high-friction reciprocal sliding. Weighing only 3.5 g/cm3 (nearly half the density of steel), it significantly reduces dynamic load on driving equipment, minimizing mechanical stress and energy consumption. Chemically stable, non-oxidizing, and highly resistant to water corrosion, it operates reliably in demanding environments with continuous temperature capabilities reaching 1,300 degrees Celsius. Available as complete ceramic-metal composite assemblies with custom dimensions, thread configurations, and micro-precision polishing, MIDDIA provides OEM/ODM manufacturing, low MOQ orders, and fast delivery for textile equipment builders worldwide.
